The potentiometric study of polyaniline (PANI) film synthesized with dopants viz. polyvinyl sulfonic acid (PVS), 𝑝-toluene sulfonic acid (𝑝TS), dodecyl benzene sulfonic acid (DBS) and composite-dopants viz. PVS–𝑝TS and PVS–DBS, has been carried out. The synthesized PANI films were characterized by electrochemical technique, UV-visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and conductivity measurement. It was found that the PANI doped with PVS gives good electrochemical properties, conductivity as well as surface morphology as compared to 𝑝TS and DBS, whereas in composite dopants the PANI doped with PVS–𝑝TS gives good polymer matrix as compared to PVS–DBS.
